Find the measure of angle a.
a. 36°
b. 108°
c. 144°
d. 54°

B

Step-by-step explanation:

The sum of the interior angles in a quadrilateral is 360°

Sum the given angles and equate to 360, that is

3x + 4x + 2x + x = 360

10x = 360 ( divide both sides by 10 )

x = 36

Hence

∠A = 3x = 3 × 36° = 108°

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

2x^2+5x+17
